What to Do When Your Boat is Making Funny Sounds

Updated: Feb 14



I don't like the sound of that

There's nothing quite like the serenity of being out on the water, but that peace can quickly be disrupted when your boat starts making strange or funny sounds. The good news is that unusual noises aren't uncommon in boats, and many of them can be resolved with proper maintenance and troubleshooting. In this blog post, we'll guide you through some common funny sounds your boat might make and what you can do to address them.


Step 1- Listen Closely


The first step in dealing with a strange noise on your boat is to listen carefully. Try to identify where the sound is coming from and what type of noise it is. Is it a squeak, a clunk, a rattle, or something else entirely? This initial assessment can provide valuable clues about the source of the problem.


Potential Engine Noises


Rattling or Knocking: If your boat's engine is making a rattling or knocking sound, it could indicate loose or damaged parts. Check for loose bolts, nuts, or any visible damage to the engine components. If you can't identify the issue, it's best to consult us at Sail & Power Maintenance and we can check this for you.


Whining or Whistling: A high-pitched whining or whistling noise from the engine area might indicate a belt or pulley issue. Inspect the belts for wear and tension and replace them if necessary.


Potential Propellor Noises


Cavitation Noise: Cavitation occurs when the propeller creates air bubbles and vibrations. It can result in a knocking or rattling sound. Check the propeller for damage or cavitation, and ensure it's properly aligned.


Whirring or Grinding: A grinding noise from the propeller could mean debris is stuck in the prop or the shaft is misaligned. Remove any obstructions and inspect the propeller and shaft for damage. If either of these problems are present then contact us and we can sort this out for you


Potential Hull and Deck Noises


Creaking or Squeaking: Squeaks and creaks from the hull or deck can be caused by stress on the boat's structure. Inspect the affected area for loose fittings, cracked fibreglass, or signs of wear and tear. Contact us if anything needs tightening or replaced


Banging or Clunking: Loose equipment or items on board can cause banging or clunking sounds as they shift with the boat's motion. Secure loose items and stow equipment properly.


Potential Steering and Control Noises


Clicking or Grinding: Unusual sounds from your steering or control system might indicate a problem with the cables, connections, or the steering mechanism itself. Inspect and lubricate the system and replace any damaged parts. If you do not feel comfortable doing it yourself, then give us a shout and we can send out a mechanic to do this before you.


How to Prevent Funny Sounds


To prevent funny sounds from occurring in the first place, adhere to a regular maintenance schedule. This includes cleaning and lubricating moving parts, inspecting belts, hoses, and cables, and ensuring all components are in good working order. Here at Sail & Power, we offer regular Maintenance and Gardiennage packages as well as one-off repairs.


Overall a funny sound on your boat can be annoying, but it's usually a sign that something needs attention rather than a cause for panic. By listening closely, identifying the source, and following the steps outlined above, you can often diagnose and address the issue yourself. However, if you're unsure or the problem persists, don't hesitate to reach out to us and we will send out one of our mechanics to diagnose and solve the issue. Regular maintenance is key to keeping your boat running smoothly and quietly, so make sure to prioritise it to enjoy many more peaceful days out on the water.
